IMPROVEMENT IN CORN-PLANTERS.

To ,all whom it may concern.- 4

Be it known that I, PETER ROGERS, of Sharon, in the county of Noble, and State of'Ohio, have invented a new and useful Improvement in Corn-Planters; and

I do hereby declare that the following is a full, clear,

and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical section of my improved machine, taken through the line a: x, iig. 2.

Figure 2 is a top or plan view of the saine.

Similar letters of reference indicate corresponding parts.

My invention has'for its object to furnish an improved machine for planting corn, which shall be sirnple in construction, reliable and accurate in operation, and convenient in use., beingso constructed and arranged that the dropping-device maybe readily thrown out of gear, allowing themachine to be turned or backed without dropping thecorn, and which maybe turned in a small space; and i It consists in the construction and arrangement of various parts of the machine, as hereinafter morefully described.

A are the fore wheels of the machine, to the axle B of which the draught is attached, by means of the ears, or couplings b', and which is connected with the bolster G by the hing-bolt c and keeper c2, the lower arm of said keeper passing thrugh a horizontal slot in said axle, as shown in iig. l.

Upon the ends of the bolster G rest, and to them are attached, the ends of the side-plates, or frames D of the machine, the lower edges of the forward parts of the side-plates, or frames D, being cutaway, as shown in iig. 1, so that they may not interfere with the movements of the fore wheels A in turning.

E are the r'ear wheels, which are rigidly attached to the axle F, so as to carry the said axle F with them in their revolution. The axle F revolves in bearings in the lower parts of the rear ends of the Side-boards, or frames D.

The axle F is formed with one or more double cranks, f', according to the number of rows to be dropped at a time, to which cranks are pivoted the forward ends of the connecting-rods, or pitmen Gr, the rear ends of which are pivoted to the lower ends of the levers H.

The levers H are pivoted to the shaft, or bar I, the ends of which are attached to the rear ends of the sideboards, or frames D.

The upper ends of the levers H are slotted, to receive the rear ends of the rods J, the forward ends of which are pivoted, or jointed tothe sliding valve-plates K, so that the said valve-plates may move back and forth horizontally while being operated bythe oscillating levers H. This construction enables the valveplates to be detached, so as not to be operated, by simply lifting the rear ends of the rods J out of the slots in the upper ends of the levers H.

The sliding valve-plates K enter and work in recesses in the blocks, or boxes L, rigidly attached to the platform M, which rests upon and is attached to the sideboards, or frames D.

The hoppcrs N are attached tothe blocks, or boxes L, directly over an opening in the upper part of the Side blocks I, so that the seed may pass from said hoppers N to the valve-plates K, which said valveplates K have holes formed through them, of such a size as to contain the exact amount of seed required to form a hill. l

Through the lower parts of each of the blocks L, or of the platform M, upon which the said blocks L rest, beneath the said valve-plates K, are formed one or two openings, according as it is desired to drop onel or two hillsfat each 'revolution of the rear wheel E, said openings communicating with the conductor-spouts O, by which the seed is conducted to the ground, and which spouts are attached to the underside ofthe platform M.

P are the furrowing-plows, which are attached to the lower ends of the standards Q, which are placed directly in front of the conductor-spouts O, and the upper ends of which are rigidly attached to the rack-shaft It, the ends of which work in Ybearings in the side boards, or frames D.

When more than one furrowing-plow is used, the lower parts of. the several standards may be connected to each other by a bar, S, to give steadiness to their movements.

The draught-strain upon the plow-standards Q is sustained by the draught-rods T, the rear ends of which are attached to the lower parts of said standards, and the forward ends of which are adjustably connected with the bolster G by having holes formed in their forward ends, passing over catch-pins attached tn said bolster, as shown in figs. 1 and 2, so that by adjusting the said rods T, the furrowing-plows may be adj ustedl to run at a greater or less depth in the ground, as may be desired. a

U are the covering-plows, which are attached 'to the lower ends of the standards V, the upper ends of which are rigidly attached to the rock-shaft W, the ends of` which work in bearings in the side-boards, or frames D.

The plows and standards U V are arranged in pairs, each pair being placed upon each side, and just in the rear of the conductor-spente O.

The standards of each pair are connected to each other by a short cross-bar, K, to give steadiness to their movements.

The draught-strain upon the standards V is sustained by the draught-rods Y, the rear ends of which are attached to the lower parts of the said standards V, and their forward ends have holes formed in them, passing over catch-pins attached to the bar Z, the end s of which are secured to the side-boards, or frames D, so that by adjusting the draught-rods V, the plows U may be adj usted to run at a greater or less depth in the ground, as may be required.

Having thus described my invention,

I claim als new, and desire vto. seeure by Letters rock-shafts RW, bar Z, bolster C, and independently- Patentadjustable rodsv T Y, all operating as described, for the 1.
